Explaining the Relationship between Exchange Rate Volatility and International Trades
최경욱 경희대학교 사회과학연구원 2010 社會科學硏究 Vol.36 No.1
In this study, we re-examine the effect of exchange rate volatility on the United States’ bilateral real exports to Canada, South Korea, and Mexico using recent econometric techniques. In this effect, we use the exchange rate volatility as measured by the Markov switching-variance process. To identify the sign of the causal effects, we use the Markov Switching Vector Autocorrelation (MS-VAR) model. This model produces mixed results. Canada, and Korea provide statistically significant, negative relationship between exchange rate variability and trade but Mexico does not.

Wii 게임을 이용한 가상현실 운동 프로그램이 뇌졸중 환자의 균형 및 보행과 상지기능에 미치는 영향
최경욱,백승민,박형기 한국신경근육물리치료학회 2022 한국신경근육재활학회지 Vol.12 No.3
The purpose of this study is to identify the effects of virtual reality exercise program with Wii on balance, walking and upper extremity function in stroke patients. Eleven subjects with stroke (an average age of 70.81 years) were participated in this study. One of three virtual reality exercises (boxing, tennis, bowling) using the Wii is performed for 30 minutes 2 times a week for 8 weeks. This study measured Timed up and go test (TUG), Berg balance scale (BBS), cadence, walking velocity, stride length, gait symmetry and box and block test (BBT) before and after 8-weeks exercise. The collected data were analyzed by using paired t-test. There were significant differences in TUG, BBS, cadence, walking velocity, stride length in the left side, gait symmetry, and BBT scores (p<.05). These findings suggests that virtual reality exercise using Wii might be effective on balance, walking and upper extremity function in patients with stroke.

한국, 중국, 미국 주식시장의 시변하는 동조화와 동태적 전이효과
최경욱,조대형 한국국제금융학회 2017 국제금융연구 Vol.7 No.2
There has emerged a situation completely contrary to the pattern, in which when the U.S. stock price rose, the Korean stock price also rose, since a global financial crisis. Such a phenomenon means that coupling of the stock markets is not fixed, but there exists a time-varying relation between the stock markets according to the environmental change of the financial market. This study investigates the time-varying co-movements and dynamic spillover effects among Korean, U.S., and Chinese stock markets since the global financial crisis. We adopt the dynamic conditional analysis and the spillover index model proposed by Diebold and Yilmaz (2009, 2012) to better capture the dynamic interconnectedness. We find that there are significant the co-movements during the analysis period. In addition, volatility spillover effects has been more rapidly changing than return spillover effects according to the financial market circumstance. 본 연구는 글로벌 금융위기 이후 한국과 미국, 중국 주식시장 간에 시변하는 동조화의 관계변화와 동태적 전이효과를 분석하기 위해서 다음과 같은 2가지의 방법론을 이용하고 있다. 첫째, 한국과 미국, 중국 주식시장 간의 시변하는 동조화 현상을 Engle(2002)의 DCC 모형을 이용하여 분석하였다. 둘째, 최근 동태적 연구방법으로 활발하게 이용되고 있는 Diebold and Yilmaz(2009, 2012)가 제안한 Spillover Index 모형을 이용하여 한국과 미국, 중국 주식시장의 수익률 및 변동성 전이효과를 분석하였다. 분석결과 글로벌 금융위기 이후 한국과 미국, 중국 주식시장 간에 동조화가 여전히 강하다는 증거를 발견하였으며, 특히 수익률 전이효과의 경우 전체 분석기간에 걸쳐 비교적 그 영향이 상당히 지속되는 것으로 나타났지만, 변동성 전이효과는 상대적으로 시간변화에 따라 관계가 급변하고 있는 것으로 나타났다.

비특이적 만성 허리통증 환자에게 체외충격파의 적용이 뒤넙다리근의 비대칭 및 허리 통증에 미치는 영향
최경욱,이시진,정성대 한국신경근육재활학회 2022 한국신경근육재활학회지 Vol.12 No.2
The purpose of this study was to investigate the effects of extracorporeal shock wave therapy on asymmetric hamstring and back pain in patients with non-specific chronic back pain. Twenty-nine subjects with nonspecific chronic low back pain were classified into experimental group (n=15) and control group (n=14). Outcome measures included hamstring length, hamstring length difference, compensative lumbar flexion and rotation, hamstring thickness, disability index, and pain intensity. The experimental group performed extracorporeal shock wave and stretching technique twice a week for three weeks, and the control group performed the stretching technique twice a week for three weeks. Extracorporeal shock waves applied 4 pressure (0.37 mJ/mm), and 2,000 shocks to the hamstring with 10 Hz. Stretching techniques are applied after extracorporeal shock wave therapy. There was a significant difference of dependent variables in the experimental group, and in the control group, there was a significant difference except for lumbar rotation. In between-group comparison, the experimental group showed signifiacnlty greater lumbar flexion and thickness of biceps femoris compared to the control group. Based on these results, we recommend extracorporeal shock wave therapy as an intervention that can reduce compensatory lumbar rotation and lengthen shortened hamstrings.

최경욱,형남원 한국은행 2010 經濟分析 Vol.16 No.3
This paper explains the feedback effect between the volatility of price variables, such as inflation rate, the interest rate, and foreign exchange rate, and the domestic economic fluctuation of Korea. For example, we show that when the uncertainty of economic gross rate increases, the level of inflation increases as a result. Additionally, we adapted a new method of spillover index calculation which was originally developed by Diebold and Yilmaz (2009) to apply the volatility of price variables to Korea. The advantage of using our method is that we are able to apply low frequency macroeconomic data, in contrast with Diebold and Yilmaz' method, which is only applicable to high frequency data. From our method, we show that the volatility spillover sharply increases from 2001 to 2008, and right after the financial crisis, the volatility spillover is shown to decrease. 본 논문에서는 물가, 금리 혹은 환율과 같은 가격변수의 변동성이 증가하였을 때 국내 경기에 어떤 영향을 주고받았는지 상호효과(feedback effect)를 분석했다. 상호효과에 대한 실증분석의 결과, 경제성장률의 불확실성이 증가할 경우 인플레이션이 높아지는 현상을 확인하였다. 또한 고빈도 자료(high frequency data)간의 확산효과(spillover)를 분석한 Diebold and Yilmaz(2009) 모형을 저빈도 자료(low frequency data)인 거시경제변수에 적용할 수 있도록 보완한 모형을 이용하여 확산효과를 분석하였다. 이를 통해 거시경제변수의 변동성을 살펴본 결과 2001년 이후 동 변수들의 변동성 확산효과가 지속적인 상승세를 보이며 2008년 하반기 국제금융위기가 표출되는 시기에 정점에 이른 후 빠른 속도로 줄어드는 것으로 파악되었다.

TFT-LCD 3차원 시뮬레이션에서의 광 경로에 대한 고려
최경욱,김기범,박우상,Choi Kyoung-Uk,Kim Gee-Bum,Park Woo-Sang 한국전기전자재료학회 2006 전기전자재료학회논문지 Vol.19 No.2
We report a novel simulation method to calculate optical transmission considering the real paths of optic introduced in a unit pixel of TFT-LCDs using three-dimensional molecular director simulation of the tensor model. The simulation of optical path transmission profile was carried out by calculating new permittivity considered the real paths of optic in liquid crystal cell. As a result, it was clarified that the electro-optic characteristics such as movement of disclination line, contrast ratio and transmittance profile show a large difference according to the viewing angle compared with the conventional method.
